Revolution in digital holography: Hologram generation based on Fast Fourier Transform (FFT)

The holographic display prototype, using VividQ software for CGH, was able to project in front of me a 3D holographic video of an animated scene built in Unity, in real-time. When I first visited VividQ, not far from Arm’s headquarters in Cambridge, I could not believe it. CGH, however, is extremely computationally intensive - it used to take days to produce a single digital holographic image. They are then presented on a micro-display that is the equivalent of the photo-sensitive film in classical holograms, and similarly replays the three-dimensional image when illuminated with laser light. In Computer-Generated Holography (CGH), the interference patterns are created digitally from a variety of data sources, from game engines to depth-sensing cameras. In the previous blog, we described how Arm is collaborating with a UK start-up VividQ to enable digital holographic displays in consumer electronics. As a physicist, this is the process I am familiar with from when I studied holography at university some years ago. This image is a perfect representation of the recorded object, because it retains the depth, parallax and other properties of the original scene. When lighting the film with a laser (figure 2), the diffraction that takes place reproduces a replay field, which to the eye appears as a three-dimensional image. The resulting interference pattern (a hologram), which encodes the whole (“ holos”) phase information about the object, is recorded on a photo-sensitive film at a very high resolution. In this process, two laser beams light the target object (figure 2). The origins of creation and reproduction of hologramsīefore the computer age, analog holograms were recorded and reproduced in a similar way to music vinyl records. First let us see how classical holograms were created.įigure 2: Classical hologram creation (left) and replay (right). But is holographic display really something from the far future? In this article, we show the recent algorithmic and computational advances that demonstrate how holographic display can now be achieved on mobile processors. Think of Stars War, Minority Report, Star Trek and many more.

Many popular Sci-Fi movies and TV shows have been inspired by the notion of holographic display when showcasing what the future of advanced visualization might look like. With increasing computing power and the emergence of new use cases like Augmented Reality (AR), there has been continuous research and development into display applications of digital holography.

Because they are incredibly difficult to copy, analog holograms have been used extensively as an anti-counterfeiting measure in credit cards, bank notes, driver licenses and in many other applications (figure 1).įigure 1: Holograms to prevent counterfeiting – on a banknote (left) and on a credit card (right). You may not notice them, but holograms have been present in our daily life for some time. Holograms are everywhere – and they will soon come to our displays
